DISK WHEEL USING DEHOUNTABLE RIM.

Application tiled August 1, 1922. Serial No. 579,017. I

My invention-relates to a device that fastens a rim to the margin of a disk, but the same device may be used on other types of wheels, besides disk wheels, and the object of the invention is to accommodate a stand ard rim to fit the margin of a disk or the i'elloe portion of a wheel.

Reference will be had ing drawing, in which Figure 1 is a radial section through half of a wheel.

Figure 2 shows an elevation of a portion of the same wheel shown in Figure 1.

Figure 3 shows a modified form of a clip fastening.

Figure 4 is an elevational view of a portion of the wheel of the form shown in Figure 3. v

Figure 5 is an enlarged sectional detail on -line 5-5 of Figure 2.

Figure (5 is an edge view of the wheel lookto the accompany ing in the direction of the arrow A, indicat-- ing the valve stem'arrahgement.

Figure 7 is a section through lug of the rim. v

Figure 8 showsthe gap between the ends of the clamping ring 7.

In the drawing, 1 indicates the hub of an ordinary automobile wheel, here shown as being a rear hub, associated with a brake drum 2. The reference numeral 3 indicates a disk which forms the web of a wheel, 4 a marginal flange that is turned on the disk which forms the seat that carries the load on the disk, 5 an ordinary quick detachable pneumatic tire rim having the side ring 6, and 7 a loose clamping ring having a radial seat 8, and an inclined seat 9 that bears on the inside of the rim 5, and this ring 7 is seated on the flange 4 of the disk 3. The ring 7 is a split ring and its ends are spaced apart as is indicated by 10 in Figure 8.

A driving lug 11 is secured to the rim 5 and fits into a perforation in flange I of the disk and passes down between the ends 10 of the clamping ring 7 and thus registers the rim and clamping ring in the same place on the disk every time.

With my device an angle valve stem is used for inflating. the pneumatic tire, and this angle valve stem is shown by 12, and the disk is cut out or apertured as is indicated by 13, to allow the direct entry of this angle valve. sidewise through the margln the driving 'on its edge for a seat of the disk, in the application and removal of the rim to and from the disk.

A series of fixed nuts 14, are secured by their flanges 15 and rivets 16 to the disk 3, and a series of screws 17 screwing into the nuts 14, clamp a series of clips 18 which hold" the rim 5 onto the margin of the disk.

The clips 18 are seated under the outer edge 19 of the rim and because of this the bolt circle of the bolt 17 must be a little smaller in diameter to accommodate the bolt head thanvis the case when I use the form shown in Figures 3 and 4. In Figures 3 and I 4 I' notch out small holes 20, at intervals, around the rim where the clamping clips occur, and thus the clip then may 'a straight clip having a bearing end 21,which bears against the edge of the notch 20, and

this arrangement permits a larger diameter bolt circleand gives a little better purchase of the screw 17 upon the clip 18.

The-clamping ring acts as an expanding 17 are screwed or tightened up and thus wedges outwardly between the disk and the rim, and makes a snug fit for the parts.

This clamping ring 7, is in efiect an adapter ring which accommodates an ordinary wire wheel rim to be used'on a disk wheel.

What I claim is 1. In a device of the class described, a demountable rim for carrying a pneumatic tire, a looseadapter ring mounted on the inside of the said demountable rim, disk wheel having a marginal flange turned for the said adapter ring with means for clamping the said parts together in fixed relationship. i

2. In a device of the class described, a disk wheel having a marginal flange turned on thedisk, a ring seated on this flange and a demountahle rim seated on said'ring, with a series of clamping clips and clamping bolts and adapted to press the demountable rim lia-tirally onto the said ring and rim of the 3. The combination with a wheel body 7 being a loose ring device when the bolts" with a I divided expansible ring mountface inclined to the plane of the wheel, a deinountahle rim fitting over said outwardly projecting portion and itself having an inwardly extending portion fitting against said inclined face, and clamping devices secured to the wheel and arranged to press the rim against said inciined face.

at. In a device of the class described, a

wheel tread adapted to carry a loose ring,

a transversely, divided riu r adapted to be seated on the saidtread ot the wheel, with the ends spaced apart; with a deiiiountable l'iin mounted on the said loose ring and trend of the wheel, and provided with a fixed pin adapted to pass between the ends of the said ring and seat in an aperture in the tread ofthe wheel to prevent rotary movement between the said parts.

The combination with a wheel body, a demountahle rim therefor ot a ti'aiisplit. adapter ring having its ends spaced apart' and interposed between the wheel body and run, and clamp ng means to force the rim onto the adapter in constrictive relation, and

the usual drivin r lu accommodated in the 5 1 t-i n i
